Physics Opportunities at a Deep Underground National Laboratory

In the past five years we have witnessed a remarkable revolution in astro-, particle and nuclear physics. The immensely significant results from the Sudbury Neutrino Observatory and those from Super-K have changed our view of physics and the Standard Model. These neutrino experiments, as well as dark matter searches and double beta decay experiments all require well shielded underground laboratories to succeed. The next generation of experiments in these fields that pursue these new physics horizons require even deeper laboratories. Several characteristic experiments will be explored and site requirements discussed. The current status of the National Underground Scientific Laboratory will be presented.
